and operation of my improved accelerator may be accurately understood it have, in the i'lrawing... shown the device in connection with :1 vehicle of the Ford. type, the device being. as previously intimated, especially designed for use in connection with this type of vehicle. lion ever, 1 do not WlSl'l to he li niteil this regard since the invention Will proiie highly effective wherever found applicable. Referring particularly to Figs. 1 and 2, the transmission cover of the ve liicle is indicated at 10 and this cover is i'losecl by the usual removable cover plate ll held in position by aplurality of" machine screws, the screws the upper corners of the plate being indicated at 152. At 13 is illnstrut the vehicle carburetor. As is usuul. this rurbureter is, shown in Fig. 5, proviizlefl with. a throttle valve ll having ii stern l5 projecting up through the top wall of the (rurlnireter and secured to said stem is e r 15 slightly bent longitudinally. A its inner encl the lever. 16 carries a. stop screw l"! adapted to cooperate with the stop 18 upon the c-a-roureter for limitingthe valve in its movement to closecl position. At outer erul the provided with an eye 19 through. which lb removnbly engaged one enri 0'5 u X'Uil 20 which ordinarily serves as u lireel; connection between the throttle eoniz-ol "til of the vehicle and the throttle Valve lover. The throttle control rod is indicated this :it this reel eniljo' f lei-meal i usual tliro In carry), employ an elongated foot lever bracket. particu arly lllust uteri in Fig. 2,

pi tel-lie resilient sheet metal bent upon itself to profile 2. substantially cylindrical. hearing or sleeve from the lower side of which diverge supporting Wings and extending from the rearmost of said Wings at its encls are laterally rlireeted ears 26. The hraelzet is of a length corresponding to the Width 01 the transmission cover plate 11 of the vehicle and, as will now be observed, is secured in position by the screws 12 for the cover plate, these screws engaging: through said ears so that the rearrnost of the Wings :25 rests upon the cover plate at its upper end While the foremost of the Wings rests (li reetly against the transmission cover. As

llllil hrought out in Fig. l, the hraclret upstands bcncath hut normally does not touch the front lioor boards of the vehicle. l-lowever, should these front door boards be stressed or become sagged. the bracket will then serve to reinforce said boards. Journaled in one end portion of the sleeve 24 is a shaft 2 .\s will be a 'ipreciated, the mouth of the sleeve is spread to receive the shaft while, owing to the resiliency of the sleeve, the shaft will be removably held therein. At one end portion. the shaft projects beyond.

the adjacent end of the sleeve to overhang the transmission cover of the vehicle and is provided with :1 depending crank 28 while from the opposite end portion ot the shaft is formed a forwardly directed foot lever 29 freely received through a transverse arcuate slot 30 in the sleeve. Adjacent its free end, the lever is curved upwardly and rcarwardly to freely project through a suitable slot in the front lloor hoards of the vehicle and, at its upper cndi. is formed with'a laterally directed terminal 31 :l'dapted to serve as a foot rest. E urroumling the shaft between the crank 28 and the adjacent cnd of the sleeve is a helical spring 3:2 inserted at one end portion through suitable openings in the wings 25 of the bracket to be secured thereto while the opposite end of said spring is engaged with the crank. Thus. this spring will, when the foot lever is depressed, serve to return said lever to its normal position.

In connection with the "arbureter 13 I employ a coupling plate 33. As particularly shown in l igs. .2 and 1-, this coupling plate is sulistantially triangular and is provided adjacent its corners with openings which. for convenience, have been indicated at 3t 35 and 36 respectively. Struck from the plate adjacent the opening 3% is a depeuding'lug 37 in which is formed an opening 38. In applying the plate the stop screw 17 of the throttle valve lever 16 is first removed, when the plate is rested uponsaid lever in such position that the opening 38 through the lug 3'? of the plate registers with the opening in the inner end of the lever which normally receives the screw. (.lonsequently, in rcplaoiug the screw it may be engaged through the lug for rigidly connecting the plate vith the inner end of the lever, llnpcrimicc has shown that Ford vehicle are equipped with carburetors of slightly dill erent type, one type being provided with a stop screw corresponding to the screw 17 and arranged in similar manner, whil another type is provided with a vertical screw only, through the throttle valve lover. I have accordingly formed the plate so that it. may be employed in connection with either of the types mentioned, the opening 34-. in the plate being adapted to receive a vertical screw to serve the same purpose as the screw 17 illustrated. The end portion of the plate provided with the opening 36 is slightly deflected upwardly to seat flat against the eye 19 of the lever and when the plate is secured by the screw 1'? said opening registers with the eye so that the adjacent lateral terminal of the rod 20 may he engaged through both the plate and the eye for connecting the plate at its adjacent corner with the outer end of the lever. Consequently, as will be seen, the plate will swing with the lever about the axis of the throttle valve stem. Extending between the crank 28 of the shaft 27 and the plate 33 is a rod 39 oti'set at one end portion to loosely engage through a suitable *opening in the free end of the crank and also offset at its opposite end portion to loosely engage through the opening 35 in the coupling plate.

Upon the throttle control rod 21 of the vehicle I employ av coupling arm 40. This arm is preferably constructed from a resilient sheet metal blank ll of the type shown in detail in Fig. 7 of the drawings. The blank is formed with a head l2 and a. yoke 43 having one arm thereof at one-side of the plane of the head while upon the ends of the yoke arms are provided reduced terminal portions 4. The head is scored medially along spaced parallel lines and then bent upwardly to provide spaced cars 45 while the end portions of the yoke arms are bent to form open loops 46. These loops are adapted to freely engage about the throttle control rod 21 to he removahly held thereon hy the reduced terminal portions 4d of the loops. Ancordingly, the coupling arm be readily inounted upon the throttle control rod to depend there from in front of the arm the yoke of the coupling arm being adapted to embrace the sleeve at the inner end of the latter arm. so that this latter arm will thus sustain the coupling arm against longitudinal movement upon the rod. In a' 'i 'ilying the coupling arm the rod 20 is first disengaged from the arm when. after the oupling arm is arranged in position the laterally directed terminal at the adjacent end of the rod is engaged through the ears ll"). The device is then ready for operation.

As will now be clear in view of the preceding description, depression of the foot lever 2.) will serve to swing the coupling plate 33 and accordingly swing the throttle lever 16 of the carhureter for opening the throttle valve while. when the foot lever is released, the spring 32 will immediately act to return the valve to its normal position. As the foot lever is depressed and the coupling plate 33 swung, the coupling element 40 will move aivay from the arm 22 upon the throttle control rod 2'1. Consequently, the accelerzn tor may be freely operated without actuating the throttle control rod and the throttle control lever at the steering wheel. However, this lever may, nevertheless, be moved essons in the usual manner for opening the throttle valve of the carburetor. its will be at once appreciated, when the lever 23 is swung downwardly to accordii'igl; rotate the throttle control rod 2l,'the arm 22 will coact with the arm to in turn-swing this arm for opening the throttle valve. As the lever 23 is returned to its normal position, the spring 32 will of course, serve to again close the valve. it will accordingly be seen that l provide an accclcratoi. which will not interfere with the use of the hand lever for manipulating the throttle valve while, ii de sired, the hand lever may be allowed to stand idle and the accelerator alone employed for manipulating the valve.

in Fig. 8 of the drawings 1 have illustrated a slightly modified form of coupling plate l7. lhis coupling plate is substantia-lly identical with the coupling plate of the preferred construction with the exception that the lateral lug 37 as en'iployed in the preferred form of plate is eliminated, the plate 47 being constructed for use alone upon carburetors of the type having a vertical screw at the inner end of the throttle valve lever thereof.
